BYT28B-400-E3/81

Diode Arrays Overview

The BYT28B-400-E3/81 is a silicon planar fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 10 A per diode in a dual common cathode configuration. The device exhibits a typical forward voltage of 1.4 V at 10 A and a maximum non-repetitive peak forward surge current of 60 A. Operating within a junction temperature range of -55°C to +150°C, it utilizes a TO-220AB package with the case connected to the cathode.
